## Model Overview

The model produces sharper visuals, eliminating blur and improving clarity across the subject or the entire frame.

## Quick Example

Let's sharpen a relatively strongly blurred image using the `Strong` mode while adjusting the `strength` parameter.

{% tab title="Python" %}

```python
import requests
import json

def main():
    response = requests.post(
        "https://api.aimlapi.com/v1/images/generations",
